    The lesser the relative molecular mass the faster the rate of diffusion because the gas are lighter and are able to move faster.

      Great Work Li Hui!
      The lower the relative molecular mass of the gas, the faster the rate of diffusion. This is due to that Kinetic Energy of the particles is inversely proportional to the relative molecular mass.
